"Step 1 - Make sure your function accepts two parameters", what am I doing wrong?

Question

I have declared the function as instructed, but when I compile it, it shows as an error. What should I correct in this code?

You will recall that by default when you declare a function the external variable names will match the function argument names.  Also you will recall that by default the first argument name is not required.  That would look something like this.
```swift
func getRemainder(a: Int, b: Int) -> Int {
    return a % b
}
let result = getRemainder(10, b: 3)
```
This challenge is trying to show you those two things.  First that you can give external argument names to help the user of your function understand what the arguments are (better than a and b) and second that when you give an external argument name to the first argument then it must be used when calling the function.  It would look something like this.
```swift
func getRemainder(value a: Int, divisor b: Int) -> Int {
    return a % b
}
let result = getRemainder(value: 10, divisor: 3)
```
